Abstract: Naturalness arguments have been a powerful guiding principle for physicists as they try to construct new theories. When applied to our
current description of the microscopic world in terms of quantum field
theory, naturalness leads to the apparent paradox of the smallness of
the electroweak scale and the cosmological constant, as compared to the
Planck scale. The hypotheses on which naturalness rests, the
consequences of relaxing some of these hypotheses, and the current
attempts to develop new paradigms beyond naturalness will be discussed.
